Patient's question:
I often have a sour odor in my mouth, usually worse in the morning when I wake up, and sometimes it's also present during the day. Is it due to stomach heat? He brushes his teeth every day, but there's no smell in his mouth, yet the air he exhales has a smell. Sometimes his tongue is red with a thick white coating in the middle. How should this be treated?Doctor's answer:
The fundamental cause of oral odor is a weakened immune system, which leads to dysfunction of internal organs and difficulty in balancing and suppressing pathogenic microorganisms that produce odor-causing compound gases. When a large number of pathogenic microorganisms reach a certain level of aggregation, they produce high concentrations of odor-causing compound gases during the absorption and decomposition of nutrients in the human body. When the concentration of these odor-causing compound gases is high, the gases enter the bloodstream and are transported unchanged to the lungs and stomach, where they are expelled from the body through the mouth and nose.
